If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Do NOT induce vomiting.

Stoddard solvent is a refined petroleumdistillate derived fromthe naphtha and kerosene carbon ranges (C7–C12) in crude oil. It is a type of ‘white spirit,’ characterized as a clear solvent absent of objectionable odors (hydrodesulfurized to remove hydrogen sulfide and mercaptans). Stoddard solvent typically contains paraffinic alkanes (saturated branched and linear), cycloalkanes (also known as cycloparaffins), and aromatic hydrocarbons. Paraffins (30–50%) and cycloparaffins (30–40%) tend to predominate, with a remaining 10–20%comprised of aromatics. The exact composition of Stoddard solvent can vary due to variations in crude oils and the refining processes. The boiling range of Stoddard solvent is approximately 148.8–204.4 °C.

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.

6-bromohexyl acetate is a colorless, refined petroleum distillate that is free from rancid or objectionable odors and that boils in the range of approximately 149.degree.C to 204.5.degree.C (300.degree.F to 400.degree.F).

Fire risk. Toxic by ingestion. Eye, skin and kidney damage; nausea; central nervous system impairment.

Flammable

Stodddard solvent was not genotoxic in a variety of assays including Salmonella typhimurium, a mouse lymphoma mutation assay, rodent bone marrow cytogenic tests, and rodent dominant lethal tests.

The hydrocarbons in Stoddard solvent vary in volatility and water solubility. Spills of Stoddard solvent would be expected to partition to soil, groundwater, and air. Smaller alkanes and aromatics will likely volatilize to the air where photooxidation can occur. Biodegradation in soil and/or water may be more likely for the larger aliphatic and aromatic hydrocarbons, although Stoddard solvent is unlikely to be readily biodegradable. Although the larger hydrocarbons in Stoddard solvent are expected to have slower elimination from biological tissues than the smaller constituents, Stoddard solvent overall would not be expected to bioaccumulate.

Stoddard solvent, as with a number of petroleum hydrocarbons, can produce kidney effects in male rats due to accumulation of a-2m-globulin. Effects observed microscopically include hyaline droplet accumulation, granular casts within medullary tubules, corticotubular basophilia, and degeneration with regeneration of tubular epithelium. These lesions, characterized as hyaline droplet nephropathy, are attributed to accumulation of a-2m-globulin, a carrier protein produced in substantial quantities in male rat livers but in negligible amounts in female rats and humans. The a-2m-globulin protein, which transports endogenous pheromones into the kidneys of male rats, also has an affinity for petroleum hydrocarbon. This mechanism is specific to male rats and is considered irrelevant to human health risk assessment. The lipophilic nature of Stoddard solvent can cause defatting of the skin. Longer or repeated exposure can increase the severity of the effects.
High exposures can produce neurological symptoms such as dizziness and lack of coordination. The specific mechanism of toxicity for this is unknown but could be similar to other short- to medium-length hydrocarbons that also produce neurotoxicity at high exposures.
The low viscosity of Stoddard solvent poses a risk of aspiration into the lungs if it is ingested, which can induce pneumonia that may be fatal.
